Because it's a political issue. The CDC is withholding the information. Lyme disease is a lifelong disease that can be treated with long-term intravenous antibiotics but it's not a "high dollar" treatment that would make insurance companies the $$$$. Most of the time doctors just prescribe 2 weeks of antibiotics and are mistreated. My wife was told that she couldn't have lyme disease because it isn't in SC, as if there is a magical fence that the ticks/disease can't cross. There are documentaries explaining the mishandling of this deadly disease; "Under Our Skin" and "Lymelife" are widely known.
